Abstract (en)
[origin: WO2012148341A2] The disclosure relates to controlling uplink transmissions according to closed loop multi-antenna techniques such as closed loop uplink transmit diversity and uplink multiple-input multiple-output (MIMO). An exemplary method for use in a user equipment (81) configured for multi-antenna transmissions comprises a step of estimating (62) reception quality of a physical channel carrying pre-coding weight information to the user equipment (61). The method further comprises a step of determining (64) that the reception quality of the physical channel is inferior if the estimated reception quality is below a threshold and otherwise considering (65) the reception quality of the physical channel to be sufficient, in a further step the UE (61) applies (52) the pre-coding weight information received on the physical channel for uplink transmission only if the reception quality of the physical channel is considered to be sufficient
